Abstract
PURPOSE:To cope with the emergency of the system without providing a signal line for interruption, by providing a means which interrupts the system independently of the presence and the absence of a data transmission enable signal when the emergency occurs. CONSTITUTION:An interrupt signal generating circuit 4 in the subcontrol system transmits an interrupt signal I to an interruption circuit 5 for an emergency. In this case, monitor data D is forcibly transmitted to a main control system 3 even if a data transmission enable signal DO does not exist. By monitor data D, an RS flip flop in the main control system 3 is set, and an output Q becomes high- level, and an interruption detection signal IC is transmitted to a host computer 10, and the main control system 3 is set to the receiving state. At this time, since the data transmission enable signal DO is forcibly outputted from the main control system 3, monitor data D for the emergency is interrupted and inputted from the subcontrol system 2, and corresponding control data C is outputted from the main control system 3.
